Perfect Construction Solutions

Committed to advancing the sustainability of new and renovated projects, SHELL Building Systems has been at the forefront of the green movement since 1972. With over 40 years vested in sustainable construction solutions, SHELL has vast expertise in the beneficial properties and specification values of many green building products, particularly pre-engineered, high-performance structural framing systems.

Our approach is to inform developers/owners, design, and construction teams about sustainable building solutions that optimally exceed CalGreen building codes and Title 24 regulations, and significantly contribute to ‘Net Zero Energy’ consumption. Our objective is to identify and provide sustainable solutions inherent in each building structure and reducing the total cost of construction by ensuring a smart return on investment.

A recognized leader in the consultation, distribution, and implementation of structural green products and pre-engineered building technologies, SHELL provides energy-conscious design reviews, cost comparison analyses, product design/engineering, shop drawings, technical support, on-site supervision, installation, training, and turn-key services.

The SHELL team has completed thousands of projects using both conventionally framed methods and pre-engineered framing systems including over 30,000,000 square feet of structural insulated panels for educational, commercial, government, and attached and detached residential developments.

Company Experience

SHELL Building Systems (SBS) is a comprehensive building resource company that specializes in the best sustainable product and service solutions the industry has to offer. With decades of industry experience and a proven record of achievements, SBS offers product design, engineering, fabrication, distribution, training, and installation for high-performance building technologies needed to erect and close-in structures. Of particular importance is our plus 40 years of extensive knowledge with framing technologies, particularly all forms of insulated structural panels and sheathing.

Founded in 1972, with offices in Northern and Southern, California, SBS has worked with developers, public agencies, architects, structural and MEP engineers, and general contractors, both domestically and in other countries, to educate them about state-of-the-art building technologies, help solve their unique project needs and provide them access to world-class products. As an OEM distributor, advisor, and installer of building systems, we have served markets worldwide including the set-up of manufacturing facilities to bring advanced building technologies and skills to other regions.

As a leader in the industry, our clients and their consultants work directly with SBS experts, who possess firsthand knowledge of framing, construction, project and construction management, development, and structural engineering. This expertise is further supported by a team of specification experts, technical product advisors, and other as-needed resources. Collectively, SBS can undertake projects from design through installation, as well as manage the critical path timelines and issues of projects. Uniquely, our capabilities may be customized to address our clients’ specific project needs as well as the needs of their project team.

SBS focuses on state-of-the-art sustainable building products and systems that are ‘tested’ and ‘proven’. Today, the efficiency and predictability of construction, the close-in time to build, the savings of reduced labor and extra steps, and the ability to offer our clients energy-efficient and ‘sustainable’ building systems are not only smart, but a necessary part of reducing the total cost of construction and lifecycle operational costs, and increasing profits.
